Awesome instructions. I was wondering where the F was the battery located. The dealer told me it is under the cluster but did not say where exactly. Hope to see more content from you.
Thanks for this, I was able to replace my battery with a $55 battery from FCPEuro (and probably could have done a $15 no name from Amazon) instead of the $300 the dealer wanted. Note that if you are having a hard time doing it through that little hole in the side of the dash, you can just undo the three T25 screws in the panel on the bottom of the dash (above the footwell), and get much more direct access from there. The cage still doesn't come out as there is a harness attached to it for some reason, but it hangs down low enough that you don't have to reach in much, and you have a much larger opening.
Auxiliary battery malfunction message comes on and off. I called the dealership for my GL 350 and I’ve been told that the auxiliary battery replacement would cost me $370. After watching this video, I feel ready to do it myself. Thank you.
Thank you so much for this. I will be trying it myself. My auxiliary battery has always showed up on the dashboard to replace it and now it’s causing issues with the Bluetooth and etc after 3 months lol. So purchased the battery yesterday for 73 dollars at the dealership. Wish me luck to install it 😅
Great video, very useful thank you. I have a UK spec 2010 model so it’s the same but opposite. Couple of points to note: 1: If you’re using a non MB battery replacement check the terminals as the one I had, the terminals were the other way round. Sounds basic but you can’t teach stupid. 2: If you’ve got hands bigger than a 5 year old then it’s a tricky procedure. The hand brake cable gets in the way and as soon as you release the holding bolt the battery and cradle drops. For those with bigger hands I’d suggest undoing the trim under the steering wheel, 3 torx screws, and getting your hands up and under and dropping the battery down that way. Fit the new battery up and under too. Saves the faffing with little piddly gap. You shouldn’t need to remove the trim totally as you can move it out the way to create the space.
Mine has been showing this for a while. Thank you for making such easy to follow content, I think mine only comes on during the winter and it turns off during the summer, so it might have something to do with the weather as my location can get very cold. I'll replace it when it comes on permanently.
Why are batteries worse in winter? But just as heat speeds up chemical reactions, cold temperatures slow them down. That's why you might feel your battery can become sluggish in winter, even though its state of charge may remain unchanged. At colder temperatures, the battery's ability to provide sufficient power to start and run a vehicle is diminished.
I'm currently having the same issue, I think I might've prematurely bought another battery because of the weather conditions as I suspected but I've kept my old battery, but the message is showing all the time even on the new battery. Please help?
1- might need to use an ODB2 device to reset the code (goto pepboys, autozone or other autostore and they usually will let use theirs to reset) 2- could mean that your main battery is starting to go bad, 3 - charging issue (need a mechanic)
I changed my Auxiliary batter because my locks were going crazy and my ac wasn't blowing cold as it used to was it the Auxiliary batery causing the problem? I didnt see any warnings about the battery at all
Hey thanks for the helpful vid. I just changed my E350s Auxiliary Battery saving me at least $400 if i had the dealership do it for me. Question, i can see a wire with a yellow fuse at the end marked no. "5" hanging loose, i'm not sure if i accidentally disconnected it. Any idea? Thanks again for the useful DIY vid.
Thanks for checking out the video/channel and leaving a comment. No, I am not sure about that wire. Do you see where it connects in the wiring harness? I would assume there would be a message on the dashboard if it was something vital to the car's system.
im new to ur chanel, i have a 2008 mercedes E350 AMG I have a, battery warning light on the dash, my7 regular battery is brand new and my alternator is good also i was looking for the auxiliar batfery buth i cant find it any idea where it could be thanks in advance
I havMBZ ML350 2012 I have replaced Starter motor then I moved the car for 4 km then I hear sound and noise comes out form the stater ?? What can I do now ... your kind help 🆘
The dimensions of the battery would be helpful... Is it seperate from the charging system ? If so, probably no need to disconnect the main battery.. If its charge just runs down over time, why cant you just re charge it ?
Im from Germany, and I try since month for the right information where to find and how to replace the auxilary battarie. Thanks a lot. Amazing video.
Oh wow! I’m glad I could help! Thanks for watching and leaving comment.
From Toronto with an E400. Great video especially when you showed the 3 different area that the battery can be.Is this battery same as a module..?
Awesome instructions. I was wondering where the F was the battery located. The dealer told me it is under the cluster but did not say where exactly. Hope to see more content from you.
Glad it helped
Great video , same location as my car. Just a note, even a weak battery will show almost full voltage in a " no load" test.
Thanks for leaving a comment! 🙏🏽

Lol, they told me $4500 to change one airbag! I did it myself, and it was so easy

Thanks for the comments!
Not nearly as easy as you do it. Finally and with your great instructions. Thank you from Texas
Thanks for sharing that, have a c250 and I'm always happy to hear that you can do this yourself and not pay them a hundred dollars an hour 👍
Thanks for watching! Yeah, that's my goal, to show people that everything doesn't have to cost a fortune just because you have a luxury vehicle.
Mine has been showing this for a while.

I am glad you enjoyed the video and it was helpful. Yeah, it might be the weather. I only started seeing issues when the weather got colder.

Great video! Can you still drive when it comes on?
It will blow up 😂@moreeshintaro6804
I'm currently having the same issue, I think I might've prematurely bought another battery because of the weather conditions as I suspected but I've kept my old battery, but the message is showing all the time even on the new battery. Please help?
Hey! Thanks for your video,it helped me a lot.What would be the cost of the Auxiliary battery...
Thank you! Glad I could help. Battery (when I got it) was around $50-60. Found on Amazon. Link in description of video.
As usual. Nice work.

Thank you so much ,but mine I have replaced the auxiliary battery the error continuously showing what could be the problem.
1- might need to use an ODB2 device to reset the code (goto pepboys, autozone or other autostore and they usually will let use theirs to reset) 2- could mean that your main battery is starting to go bad, 3 - charging issue (need a mechanic)
I changed my Auxiliary batter because my locks were going crazy and my ac wasn't blowing cold as it used to was it the Auxiliary batery causing the problem? I didnt see any warnings about the battery at all
May it cause a problem if I forget to disconnect the main battery before proceeding to replace the auxiliary one?
You should be fine.
12,5 volts is 75 percent charged ,12.7 is 100 percent charged

It took me 4 hours my first time.
Took me a while too
Hey, by any chance do you know the location of an axillary battery in a 2014 CL 550?

i have 2009 ml350 suv do you have to reset anything when you change aux battery
No, I don't recall having to reset anything.
I've replaced my battery but the message hasn't gone away? What could be the issue?
Good vid but you cant get ELECTROCUTED from a 12v battery
Very helpful video, thank you!

Why does mine still say malfunction even tho I replaced the battery with a OEM Mercedes battery
THANKS SO MUCH!!
Glad I could help!
Ty~
Fire car 🔥
Thanks 🙏🏽
There is no way to electrocute yourself with 12 Volts. A short circuit is much more dangerous.
The dimensions of the battery would be helpful...
Is it seperate from the charging system ? If so, probably no need to disconnect the main battery..
If its charge just runs down over time, why cant you just re charge it ?
You need the hands of a 6-year-old to actually get in there and do anything.
Twss
AMG and you're pushin' that thing on (C) mode?! Man, c'mon, you play too much..
I can tell it in a minute quickly. I spent 10 minutes of time. time thief!
